# Key to Supported Formats Table

The supported formats table includes the following information:

Column | Description
--- | ---
Format Name | The format name that is returned by file format detection. In the C API, these values are defined in the `ENdocFmt` enumeration in `adDocFmt.h`. In the .NET API these values are defined in the `KeyView.Filter.DocFormat` enumeration. In the Java API these values are defined in the `com.verity.api.DocFormat` enumeration. In the C++ API these values are defined in `keyview::Format`, used in `DetectionInfo` which is returned by `Session::detect()`. In the Python API these values are defined in the `keyview.filter.DocFormat` enum.
Number | The format number that is returned by file format detection. This is the value associated with the Format Name in the relevant enumeration. The format number is used in the configuration file, formats.ini, to specify the reader to use to filter the format.
Description | A short description of the file format.
MIME Type | The MIME type (if any).
Extension | A list of common file extensions for the file format. NOTE: This is not a complete list of file extensions. File Content Extraction does not distinguish between file types based on their extension. Instead, it detects the file format based on the file content. This is more reliable because content cannot always be predicted from the file extension, and because some file extensions are associated with multiple formats.
Encrypted | Many file formats offer encryption to protect file content. This column specifies whether File Content Extraction can detect encrypted forms of the file format. If there is a check mark in this column, the encrypted property might be set in the results from format detection. In the C API, see the `ulAttributes` member of the `ADDOCINFO` struct, and the `kEncrypted` enumerator of the `ENDocAttributes` enumeration. In the .NET API, see the `Encrypted()` method of the `DocInfo` class. In the Java API, see the `isEncrypted()` method of the `DocFormatInfo` class. In the C++ API, see the `encrypted()` method of the `DetectionInfo` class. In the Python API, see the `encrypted` attribute of the `DocInfo` class.
Metadata | Specifies whether File Content Extraction can extract metadata from the file format.
File Class | The file class. In the C API, these values are defined in the `ENdocClass` enumeration in `adinfo.h`. In the .NET API these values are defined in the `KeyView.Filter.DocClass` enumeration. In the Java API these values are defined in the `com.verity.api.DocClass` enumeration. In the C++ API these values are defined in `keyview::Category`, used in `DetectionInfo` which is returned by `Session::detect()`. In the Python API, these values are defined in the `keyview.filter.DocClass` enum.
